Patented Dec. 17, 1929 UNITED STATES PATENT OFFICE OSCAR GREENWALD, OFBROOKLYN, NEW YORK, ASSIGNOR TO FAICHNEY INSTRU- MENT CORPORATION, OFWATER'IOWN, NEW YORK, A CORPORATION OF NEW YORK POCKET-THERMOMETER CASEApplication filed December 15, 1927.

This invention relates to improvements in pocket thermometer cases forthe use of physicians in carrying thermometers. More particularly thisinvention relates to 1mprovements in fountain pen type cases orcontainers for thermometers.

The object of the invention is to provide an improved holding member orspring member adapted to be inserted in the standard type and sizefountain pen pocket thermometer case for the purpose of preventing thethermometers from rattling and breaking.

My improved pocket thermometer case is characterized by the fact that asingle resilient holding member is interposed between the thermometerswhereby a more efficient and more economical type of holding member isprovided.

Accordingly my invention embodied in a pocket thermometer pocket caseconstructed and arranged as hereinafter set forth and as illustrated inits preferred form in the accompanying drawing in which Figure 1 is aview of the pocket thermometer casing, with parts in section.

Figure 2 is a perspective view of the spring holding member.

Figure 8 is a plan view of the cap which carries the member.

In the drawing the reference numeral 4 denotes the barrel of a fountainpen which may be closed by the well known type of clip cap 5. In themouth of the barrel there is inserted a plug or cap 6 having twoapertures 7 and 8. The plug 6 further carries a holding and separatingmember 9 in the form of thin strip or blade preferably of spring brass.The blade 9 is cut to provide two springs 11 and 12 which are bentoutward from the blade substantially parallel therewith. The springs arebent in opposite directions so that the spring 11 is on one side of theblade and the spring 12 on the opposite side of the blade.

The plug 6 and blade 9 form a separating and holding member which isinserted in the barrel 4, the plug 6 fitting tightly in the mouth of thebarrel. The numerals 13 and 14 denote two thermometers, the grading ofwhich is not shown. 4

Serial No. 240,087.

In use the thermometers are inserted in the apertures 7 and 8 and pushedinto the barrel. In passing into the barrel, the thermometers depressthe springs, which latter engage the thermometers with sufficient springpressure to separate and hold the thermometer firmly in the barrel 4.When the thermometers are withdrawn. the springs spring outward from theblade, but are again easily depressed when the thermometers arereinserted.

The blade member is cut and shaped in a single operation and inserted ina groove 15 in the plug 6 in which it is held firmly.

It is obvious that the invention is not limited in its use to fountainpen type pocket thermometer casings but may be used for other purposes.

I claim:

A thermometer casing including a barrel formed to contain a pair ofthermometers, a plug in the barrel provided with apertures to receivethe thermometers therethrough, and a member secured to the plug anddisposed in the barrel between the apertures, said member having spacedintegral tongues struck out therefrom, one of the tongues beingconnected to the member adjacent an end of the latter and the othertongue being connected to the member adjacent to the center of thelength of said member, the'tongues being disposed on opposite sides ofthe member.

OSCAR GREENWALD.
